shows that the power intensity had a large
influence on the mechanical response of the skin and pulp. However in strategy 1 firmness significantly increased (P< 0.05) with
the specific power, whereas in strategy 2 firmness decreased with
the specific power. This could be due to the fact that MWHA drying
with power control made less firm the product structure (good
structure for dried tomato) compared to MWHA drying without
power control. So MWHA drying with microwave power control
improved tomato quality. To have weak mechanical changes of tomato after MWHA drying, an osmotic pretreatment will be necessary as was doneHeredia et al. (2007)on the tomatoes before the
dehydration
